Disk-drive sparing

Disk-drive sparing has a basic structure associated with RedundancySet.

The disk-drive sparing RedundancySet structure is composed of one instance class and three association classes:

Instance class:
  • IBMTSSVC_StorageRedundancySet (Extended from CIM_StorageRedundancySet)
Association classes:
  • IBMTSSVC_StoragePoolExtentDependency represents the association between IBMTSSVC_DiskDriveExtent and IBMTSSVC_ConcreteStoragePool.
  • IBMTSSVC_HostedRedundancySet represents the association between IBMTSSVC_StorageRedundancySet and IBMTSSVC_Cluster.
  • IBMTSSVC_MemberOfRedundancySet represents the association between IBMTSSVC_DiskDriveExtent and IBMTSSVC_StorageRedundancySet. The DiskDriveExtents form the redundancy set of a StoragePool.
